when i first start my car it takes a second or 2..and when it finally fires it kinda boggs out then its fine....if i go 2 move the car after its been warming up and barely step on the gas (u know like as if im in a parking lot) it'll sputter then get going....i use injector cleaner alot so...im sure they are fine..just changed cap wire and rotors...my plugs were a little white, they were gapped at .40 so i dont really think im running lean....any body have any ideas??

 

Try unplugging the MAF and EGR vacuum line and see if that helps.

 

If the plugs were "white" then you must be a little on the lean side. But, I'd try an o2 sensor.

 

Make sure all your wires are good, even if they are new...

Could also be the ECM. My wife's car did exactly what you
describe....it was the ECM even though it would offer no codes.
